UTIA Scientists Publish Paper on Role of Citizen Science in Addressing Agricultural Challenges

Dr. Sean Ryan, a postdoctoral researcher in the EPP Department, Dr. DeWayne Shoemaker, and an international team of more than three dozen researchers published a paper highlighting the potential of citizen science to address pressing research challenges in agriculture and food systems. One key to capitalizing on such efforts, the researchers find, may be to build stronger ties between citizen science and agricultural extension efforts. A press article summarizing the article is here and a free copy (open access) of the original paper can be downloaded from the journal web site.

Be on the Lookout for Grapevine Leaf Rust in Tennessee

Dr. Zach Hansen published an article in the November 2018 National Plant Diagnostic Network newsletter. Grapevine leaf rust was observed for the first time in Tennessee in September 2018. The disease was found on grape seedlings at large box stores in several counties in middle and east Tennessee. Dr. Hansen suggests that growers, industry professionals, diagnosticians and extension personnel should be aware of the disease and should be on the lookout for it. For the full article, click here.

Tennessee Tick Survey by Dr. Trout Fryxell and David Theuret

A tick survey study in Tennessee by Dr. Trout Fryxell and graduate student David Theuret highlighted in Entomology Today. The study revealed that one in six cattle and at livestock monitoring locations in all regions of the Tennessee have ticks. For more details, please see summary article Tick Surveillance Project Offers Model for Monitoring Livestock. The original article can be found here.

Dr. Hale and Dr. A. Windham Invited Speakers for UTIA Turf and Ornamental Field Day

Frank Hale and Alan Windham attended UT Turf and Ornamental Field Day on Thursday at the Plant Science farm on Alcoa. They averaged 50 persons for each of four presentations, which covered new and noteworthy insect pests and diseases such as emerald ash borer, boxwood blight, rose rosette and others. Over 500 turf and grounds maintenance professionals attended the field day.

Development of Novel DNA-Based Methods for Detection of Bt Resistant Fall Armyworms

During the past 22 years, pest control efficacy and the potential for higher net returns have driven a global increase in the adoption of transgenic crops which produce insecticidal proteins (Cry and Vip toxins) from the bacterium Bacillus thuringiensis (Bt crops). In the US alone, Bt corn and cotton adoption represent >80% of the national acreage devoted to the two commodities, which has unfortunately led to increasing selection pressure for evolution of Bt toxin resistant insect pests. One such devastating pest is the fall armyworm (Spodoptera frugiperda) which has become a growing threat to the use of transgenic corn technology in the Western Hemisphere and more recently the African continent. The fall armyworm is the insect pest with the highest

Congratulations to Dr. Denita Hadziabdic Guerry – Fulbright Scholar!

Several indigenous crop species have the potential to become foods of the future and need to be integrated into existing agricultural research. Dr. Denita Hadziabdic Guerry was selected for a Fulbright award to the African Regional Research Program to study an indigenous crop, frafra potato (Solenostemon rotendifolius), as an alternative food source. She will spend four months in Ghana working closely with her collaborator at the University of Ghana (UG), Dr. Naalamle Amissah, to evaluate genetic diversity of frafra potato populations in Ghana and surrounding sub-Saharan African countries where this species is cultivated. This is quite an innovative project that involves studying traditional subjects while providing hands-on experiential learning experiences for faculty, staff, and students at the University of Ghana. Congratulations, Dr. Guerry!
